We have several goats that are suddenly shedding a lot, and two that have shed so much so quickly that Im starting to see the skin on their backs. Their skin looks fine, no itching or flaking. The tail tips aren't bald and they don't have balding around the eyes. I'm wondering if this is a copper or zinc deficiency? A few factors: 1. we have 2 very mild seasons and our goats do not grow winter coats 2. we only have multi species pre mixed loose minerals available in our area (horse, cow, sheep, goat) 3. we lost several babies last year due to selenium deficiency so we've given BoSe twice now (3 months apart) have seen some improvement in heat cycles and coat condition 4. copper bolus is not available here, but we've ordered it from the States and it will arrive next month So, would you all just wait for the copper bolus or start giving zinc? I know selenium overdose can cause hair loss, but I'm inclined to say that's not it. We have very poor subtropical soil where there is lots of clay and run off. Our water source is mountain river water and has no smell, no taste and doesn't leave stains or deposits on the sink. The goats are pasture fed year round except for sprouted corn for the milkers. Very little alfalfa or other leguminous forage.
